CI-red root cause (classification a: my round-4 change fails in the clean/cold CI env): get_gitea_token_for_login hard-required PyYAML (`import yaml`), which is absent on CI's node:24-alpine (python3 without py3-yaml). Round-4's --login override cases were the first to exercise that path, turning the mosaic package test (test:framework-shell -> test-pr-review-gitea-comment.sh) RED. Fix: add an indentation-aware line-parser fallback that resolves the SAME per-name token PyYAML would from tea's flat `logins:` list; PyYAML stays the fast path. This also repairs a latent production defect (--login overrides were silently unusable on any PyYAML-less host). Auditor blockers folded into the same round-5: 1. issue_url vs pull_request_url shape (correctness): Gitea populates WEB (html) URLs in issue_url/pull_request_url, not API paths, and a PR-conversation comment carries pull_request_url (issue_url empty). Verification now accepts either web shape scoped to the repo slug + number, so a durable write is never rejected for URL shape. Test stubs now emit the REAL Gitea web shapes. 2. Cross-host credential binding (security): get_gitea_token_for_login now takes the repo host and requires the matched login's configured URL host to equal it; an override login configured for a different host FAILS CLOSED instead of sending a cross-host credential. Regression tests added to both suites. 3. Non-exhaustive enumeration (false-fail): removed the redundant, non-exhaustive post-verification list enumeration (gitea_fetch_all + confirm_*_enumerable) from both wrappers; the exact-id GET is authoritative. Pagination cases dropped; a guard asserts no list enumeration is performed. 4. Trap clobbering / temp-file leak (security/hygiene): removing the nested enumeration eliminates the RETURN-trap nesting that clobbered caller cleanup; remaining RETURN traps are single/non-nested and clean up on all exit paths. Temp-file leak regression tests (success + failure paths) added to both suites. 5. README: corrected the exhaustive-pagination claim and documented host-bound --login selection. Preserves every round-2/3/4 fix (explicit --login fail-closed at all write sites, token->identity attribution seam). Gates: cold `pnpm turbo run test --filter=@mosaicstack/mosaic` green (14/14); full test-*.sh suite green with AND without PyYAML; bash -n, shellcheck -x -S warning, prettier --check README clean.

CLI package for the Mosaic self-hosted AI agent platform.
Usage
mosaic wizard # First-run setup wizard
mosaic gateway install # Install the gateway daemon
mosaic config show # View current configuration
mosaic config hooks list # Manage Claude hooks
Headless / CI Installation
Set MOSAIC_ASSUME_YES=1 (or ensure stdin is not a TTY) to skip all interactive prompts. The following environment variables control the install:
Gateway configuration (mosaic gateway install)
| Variable | Default | Required |
|---|---|---|
MOSAIC_STORAGE_TIER |
local |
No |
MOSAIC_GATEWAY_PORT |
14242 |
No |
MOSAIC_DATABASE_URL |
(none) | Yes if tier=team |
MOSAIC_VALKEY_URL |
(none) | Yes if tier=team |
MOSAIC_ANTHROPIC_API_KEY |
(none) | No |
MOSAIC_CORS_ORIGIN |
http://localhost:3000 |
No |
Admin user bootstrap
| Variable | Default | Required |
|---|---|---|
MOSAIC_ADMIN_NAME |
(none) | Yes (headless) |
MOSAIC_ADMIN_EMAIL |
(none) | Yes (headless) |
MOSAIC_ADMIN_PASSWORD |
(none) | Yes (headless) |
MOSAIC_ADMIN_PASSWORD must be at least 8 characters. In headless mode a missing or too-short password causes a non-zero exit.
Example: Docker / CI install
export MOSAIC_ASSUME_YES=1
export MOSAIC_ADMIN_NAME="Admin"
export MOSAIC_ADMIN_EMAIL="admin@example.com"
export MOSAIC_ADMIN_PASSWORD="securepass123"
mosaic gateway install
Runtime launchers
mosaic claude # Launch Claude Code with Mosaic injection
mosaic yolo claude # …with --dangerously-skip-permissions
mosaic codex | opencode | pi
mosaic claudex (EXPERIMENTAL)
Runs GPT models inside the Claude Code harness by pointing Claude Code at a
local claude-code-proxy that
translates the Anthropic Messages API to a ChatGPT-subscription (Codex OAuth)
backend. This is not Anthropic Claude — model behavior, tool use, and output
quality may differ. Intended for evaluation, not production delivery.
mosaic claudex # launch (prompts through the proxy readiness gate)
mosaic yolo claudex # …with --dangerously-skip-permissions
mosaic claudex --print "hello" # trailing args are forwarded to Claude Code
Prerequisite: the claude-code-proxy binary must be installed and
authenticated (claude-code-proxy codex auth …). mosaic claudex runs a
preflight that verifies the binary, the OAuth state (triggering a device re-auth
if needed), and a trusted local listener before launching; it fails closed
if the proxy cannot be brought up with a verified identity.
Isolation (never touches your real Claude state). claudex always launches
against an isolated CLAUDE_CONFIG_DIR (default ~/.config/mosaic/claudex/home).
The ambient CLAUDE_CONFIG_DIR is deliberately ignored, and a guard proves the
resolved dir can never be — or live under — the real ~/.claude. A claudex
session therefore cannot mutate your normal Claude Code config.
No token leakage. claudex never reads the proxy's credential file. Claude
Code is handed only ANTHROPIC_AUTH_TOKEN=unused pointed at the loopback proxy;
the entire credential-bearing env family (ANTHROPIC_*, AWS_*, GOOGLE_CLOUD_*,
GOOGLE_APPLICATION_CREDENTIALS, *_TOKEN, *_KEY, *_SECRET, …) is stripped
from the composed environment. The Bedrock/Vertex routing switches
(CLAUDE_CODE_USE_BEDROCK, CLAUDE_CODE_USE_VERTEX, and the _SKIP_*_AUTH
pair) are force-removed regardless of value — otherwise their mere presence
would route Claude Code to the real Anthropic API via AWS/GCP and bypass the
proxy. The proxy holds the real OAuth credential.
Model tiers (override via env).
| Tier | Env var | Default |
|---|---|---|
| primary (opus/sonnet) | ANTHROPIC_MODEL |
gpt-5.6-sol |
| small/fast (haiku) | ANTHROPIC_SMALL_FAST_MODEL |
gpt-5.6-luna |
Operator-provided values win over the defaults. Additional overrides:
MOSAIC_CLAUDEX_CONFIG_DIR (isolated config dir), ANTHROPIC_BASE_URL (proxy
endpoint).
Hooks management
After running mosaic wizard, Claude hooks are installed in ~/.claude/hooks-config.json.
mosaic config hooks list # Show all hooks and enabled/disabled status
mosaic config hooks disable PostToolUse # Disable a hook (reversible)
mosaic config hooks enable PostToolUse # Re-enable a disabled hook
Set CLAUDE_HOME to override the default ~/.claude directory.
